star

1 light can travel around seven times in one second .2 gravity can pull hydrogen atoms together , smashing and fusing into heavier helium atoms .3 mid sized stars like the sun turn into white dwarfs.4.

nuclear fusions generates an enormous amounts of energy 5. when the sun turns into a red giant it will be big enough that it will engulfs the solar system.
